Derrick Shale Shaker Replacement Manufacturer – API Screens & Shakers

In the industrial equipment sector, Derrick high-frequency shale shakers are renowned for their exceptional performance in handling wet, fine-grained materials. However, the market now offers robust, high-quality alternatives from Chinese manufacturers that fully comply with API standards. With 26 years of R&D in solids control, Xi'an Tianrui Solids Control produces mud shale shakers that can replace the entire Derrick shale shaker units and their supporting products, such as shaker screens and complete equipment for models like FLC 500, FLC 2000, Hyperpool, etc.

How Do Derrick Shale Shakers Work?

Derrick shakers are designed with multi‑deck, high‑frequency concept, focusing on fine particle separation and high‑viscosity fluid handling. Widely used in mining, oil drilling, tailings recovery, etc. The working process can be summarised as “splitting – feeding – screening”.

1. Diversion: The drilling mud or slurry first enters a distribution manifold, where it is evenly split into multiple streams (usually matching the number of screen decks).

2. Feeding: The diverted slurry is evenly and thinly spread on the feed end of each screen surface through the feeder.

3. Screening: Under high-frequency and small-amplitude vibration, the materials on the screen surface are thrown up and move forward. Fine particles quickly sink to the bottom of the material layer and pass through the shaker screens to become undersize products; coarse particles are discharged from the end of the screen surface to become oversize products.

Unique Screening Structure Design

A.  Stack Sizer® (Stacked High-Frequency Fine Screen) - Mainly Used in Mining/Metallurgy

1. Multi-layer Independent Screen Surfaces: A single equipment is vertically stacked with 5 layers of independent polyurethane screen plates.

2. Independent Tensioning and Buffering: Each layer of shaker screen is independently tensioned, and there are rubber buffer blocks between layers.

3. Principle: When the exciting force is transmitted, each layer of shaker screen can independently generate high-frequency vibration. This design eliminates inter-layer interference, making the total effective screening area of the 5-layer screen surface 5 times the equipment footprint.

4. Material Flow Direction: The feed enters from the top and is evenly distributed to each layer. Fine particles fall through the shaker screens, and coarse particles are discharged from the end of each layer.

5. Application: It is mainly used for classification in grinding circuits (such as iron concentrate and copper ore), which can effectively remove over-crushed fine mud and improve the efficiency of ball mills.

B. FLC / Hyperpool Series (Flat Plate Shale Shaker) - Mainly Used in Oil Drilling/Solids Control

1. Flat Screen Design: Adopts a full flat or slightly inclined screen box design, with extremely high utilization rate of effective screening area (up to more than 90%).

2. Pre-tensioned Screens: The shaker screens are pre-tensioned on the metal frame before leaving the factory (similar to a drum head).

3. Principle: Pre-tensioning ensures that the shaker screens will not loosen under high-frequency vibration, maintains the stability of the screen hole shape, prevents "screen clogging", and provides a more accurate cut point.

4. Deflector System: A special mud deflector is designed inside, which uses fluid dynamics principles to make the mud quickly cover the entire screen surface and avoid short circuits (i.e., the mud flows out directly without filtration).

💡 How to Choose and Precautions

When choosing a manufacturer, you can pay attention to the following points according to your specific needs:

1. Confirm Model: Derrick has a variety of series (such as FLC series for oil, Stack Sizer or Hyperpool for mining). Please clarify whether you need to replace the shaker screens or the entire unit, as well as the specific model.

2. Confirm Parameters: If choosing accessory replacement, be sure to confirm the specific model of the original equipment, shaker screen size, tensioning method, etc., to ensure that the new accessories can be directly installed and used. Manufacturers like Tianrui Solids Control support customization according to size.

3. API Certification: If it is used for oil drilling projects, be sure to confirm that the alternative shaker screen supplier has API Q1 / API RP 13C certification to ensure compliance.

4. Material and Craftsmanship: Inquire about the stainless steel material of the shaker screens (304 or 316L), bonding process (whether it is easy to degum), and effective screening area, which directly affect the service life and screening efficiency.

TR Solids Control has 26 years of experience in the solids control industry, with API/ISO certification and is a qualified supplier of CNPC. It can produce high-frequency dry shale shakers directly interchangeable with models such as Derrick FLC503, and a full range of wave shaker screens (20–400 meshes). It supports customization of G-force, angle, and shaker screen size, providing one-stop delivery + on-site installation guidance. The products are widely used in oilfield drilling, drill cuttings reduction, and shield mud treatment.
